  • the invention relates to a mobile mixing plant constituting one of the elements of a mobile, heavy, autonomous and self-erecting plant for the manufacture of concrete, said plant possibly, for example, further comprising a mobile storage unit for 'aggregates, and at least one mobile cement silo, as well as means of storage and distribution of water and means of storage and distribution of adjuvants.
  • a plant comprising a cement tank transported in a horizontal position and provided with a mixer.
  • This tank is provided with a beam with a stiffening element receiving a set of wheels.
  • the tank after lifting by hydraulic means via a mast, is supplied with aggregates by dump trucks.
  • Such an installation is therefore not autonomous and, moreover, it requires for its installation lifting means which are generally not available on site. It also supposes the availability of local water and electricity networks, additives, construction of ramps and civil engineering additives, destroying the formation of mobility.
  • FR-A-2,607.053 Another proposal (FR-A-2,607.053) provides for a concrete mixer articulated on a framework of a block for aggregates.
  • the mixer can thus be raised so as to allow the passage of the mixing tanks which will serve the site.
  • the aggregate block is fitted with transport wheels and the mixing block can be placed, after being folded up, on a towing vehicle.
  • a cement block consists of silos transported separately.
  • the mixer-block assembly for aggregates has, after folding, a very long longitudinal dimension which prevents access to sites served by a narrow road and / or laces.
  • the joint of the mixer is bulky and fragile.
  • the supply of aggregates is done by a trolley which is itself bulky during transport.
  • the installation of the plant requires perfectly leveled soil and sufficiently load-bearing, so that the installation takes several days.
  • the present invention therefore aims to provide a mobile plant for the manufacture of concrete, equipped with the same technology as the stationary plant, which does not have the drawbacks of known plants and which is in particular completely autonomous, easily transportable, including included on difficult roads, which does not require special equipment for its installation, and which can be implemented on site in a very short time of the order of a day, with all the ancillary elements pre -wired, pre-assembled and on normal ground.
  • Another object of the present invention is to provide a mobile mixing station, pre-wired, self-erecting without a crane by a set of hydraulic cylinders and slide systems, allowing its self-lifting in full autonomy.
  • the mobile mixing plant is characterized in that it comprises a mobile mixing block and a conveyor frame, the conveyor frame taking the form of an inverted U-shaped profile, the two wings of which are equipped with guide means. vertical and lifting of the kneading block and the core of which has a through recess inside which the telescopic kneading block is movably mounted, said kneading block cooperating with the guidance and lifting means so as to occupy a position low transport in which it is locked inside the wings of the profile and a high working position in which it is locked in suspension above the through recess of the transport chassis so that the space left free between the wings of the profile allows the passage of truck mixers.
  • the vertical guide means of the conveyor frame of the mobile mixing plant can be constituted by lateral slides, mobile or not, which cooperate by means of intermediate slides with integral slides of the kneading block
  • the means for lifting the kneading block can be constituted by hydraulic jacks, preferably double acting
  • the means for locking the kneading block in the high position can be constituted by retractable stops integral with the kneading block and which come to bear on the periphery of the through recess of the conveyor frame
  • the means for locking the kneading block in the low position can be constituted by centralizers, preferably with frustoconical end, which penetrate at the entry of larger section of orifices integral with the conveyor frame.
  • Figure 1 is a schematic elevational view of a mobile plant according to an exemplary embodiment of the invention, in the working position;
  • Figure 2 is a plan view of the powerhouse of Figure 1;
  • Figure 3 is a schematic elevational view of a semi-trailer carrying the aggregate block of the power plant of Figure 1;
  • Figure 4 is an end view of the assembly of Figure 2;
  • Figure 5 is a schematic elevational view of a semi-trailer carrying the mixing block of the plant of Figures 1 and 2;
  • Figure 6 is an end view of the semi-trailer of Figure 5;
  • Figure 7 is a schematic elevational view of a semi-trailer carrying a silo of the plant of Figures 1 and 2;
  • Figure 8 is a view of end of the semi-trailer of FIG. 7;
  • Figure 9 is a very schematic side elevational view of the conveyor frame in the transport position;
  • Figure 10 is similar to Figure 9, but partially in section;
  • Figure 11 is similar to Figure 10, but for the working position; and
  • the heavy, autonomous and self-erectile mobile power plant for the manufacture of concrete consists of an aggregate block 1, a mixing block 2 and at least one cement silo 3.
  • the aggregate block is advantageously divided into a plurality of silos equipped with pneumatic helmets and may include risers making it possible to adjust its capacity.
  • the aggregate block 1 consists of sixteen individual silos 4 separated by partitions and each provided with a pneumatic helmet 5. It is provided with a longitudinal conveyor weighing belt 6 of large width ensuring simultaneously weighing aggregates. It is also equipped with removable risers 7 allowing its capacity to be modified. It is powered by skips or by carpet, depending on the extensions. Metal tipping ramps are incorporated into the frame and deploy automatically upon arrival on site (left or right) for versatile attachment.
  • the aggregate block 1 is integral with a towed chassis 8 (FIGS. 3 and 4) equipped with stabilizing crutches 9 and working crutches 10.
  • the chassis 8 possibly also carries a compressor group 11 and a generator 12.
  • the mixing block 2 is integrated into a towed chassis 13 (FIGS. 9 to 11) which can be raised by lifting cylinders 14 and stabilized by stabilizing cylinders 15 which, in the working position of the mixing block 2, are immobilized for example , by triangular gussets (not shown) which avoid any lateral movement of the entire structure.
  • the mixing block 2 and the chassis 13 assembly constitutes the mobile mixing center.
  • the conveyor frame 13 takes the form of an inverted U-shaped profile, the two wings 31 of which are equipped with vertical guide and lifting means 17 of the kneading block 2 and the core 32 of which has a through recess inside which the telescopic kneading block 2 is movable.
  • the kneading block 2 is supported by a platform 16 which can be lifted by said lifting means, namely hydraulic jacks, preferably double acting, arranged at the four edges of the wings 31 of the conveyor frame 13 and which bear on the four corners of the underside of the platform 16.
  • said lifting means namely hydraulic jacks, preferably double acting, arranged at the four edges of the wings 31 of the conveyor frame 13 and which bear on the four corners of the underside of the platform 16.
  • the mixing block 2 is capable of occupying a low transport position (FIGS. 5, 6, 9 and 10) and a high working position (figure 11).
  • a passage 33 in the shape of an inverted U is formed under the kneading block 2 for the passage of the mixer trucks 18.
  • the height of this passage is 4.20 meters while the height in the low position is equal at 4.30 meters.
  • Means for locking the kneading block in position are provided both in the high position and in the low position of the kneading block 2. In the high position, these locking means are constituted for example by horizontal jacks 30 integral with the kneading block 2 and which come to bear on the periphery of the through recess of the conveyor frame 13 when the kneading block 2 has reached its maximum height.
  • the locking means of the kneading block 2 in the low position can on the contrary be constituted by centering elements at the end, preferably frustoconical, integral with the kneading block 2 and which during the descent of the kneading block 2 come into screw vis-à-vis the entry of larger section of orifices integral with the conveyor frame 13 and penetrate therein.
  • any other means locking in the low position or in the high position can be envisaged.
  • the means for lifting the kneading block 2 are arranged means for vertically guiding the kneading block so as to facilitate its passage from the high position to the low position and vice versa.
  • These guide means are constituted by lateral slides which may or may not be movable and which cooperate via intermediate slides with slides integral with the kneading block 2.
  • the slides 34 of the kneading block, 35 of the conveyor frame, and the intermediate slides 36 include removable connecting means (not shown) which join them together or not so as to be able to make their movement dependent on the movement of the adjacent slide.
  • the intermediate slide 36 slides inside the slide 35 of the conveyor frame 13.
  • the lower end of the intermediate slide 36 arrives at the lower end of the slide 35 of the conveyor frame 13, it drives the latter upwards over a short distance represented by d in FIG. 11.
  • the slide 34 of the mixing block separates its movement from that of the intermediate slide 36 so as to be able to continue its travel and drive the mixing block 2 to a maximum height.
  • the mixing block 2 which can optionally be clad, is equipped with an inclined conveyor or skip 19 which, in the low position, receives the aggregates transported by the belt 6 and, in the high position, pours them into the mixer.
  • the block 2 also includes articulated inspection and maintenance walkways 20. These walkways can for example be mounted for rotation about a horizontal axis so that they constitute one of the walls of the kneading block 2 in position bottom of the block and a gangway in the high position of the block.
  • the block further includes a water scale 21 provided with weighing means and supplied by a water tank 22, an add-on scale 23 and a cement scale 24 equipped with a weighing device.
  • the adjuvant scale 23 is controlled by specialization and timed. It has a washing ramp.
  • the chassis 13 also carries a control cabin 25 with a steering and management computer.
